[Bug target/84772] powerpc-spe: Spurious "is used uninitialized" warning, or possibly incorrect codegen for va_arg(long double)


https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84772

--- Comment #7 from Zack Weinberg <zackw at panix dot com> ---
I no longer remember enough about GIMPLE to comment on your actual proposed
fix, but I do have a small nitpick on the test case:

+    va_arg (ap, long double);                  /* { dg-bogus "may be used
uninitialized in this function" } */  

I think that needs to be just { dg-bogus "used uninitialized" }, as you might
get either the "may be used initialized" or the "is used uninitialized"
message.
